PCR assays for the detection of members of the genus Ilarvirus and family Bromoviridae
چکیده انگلیسی

A PCR assay was developed for the universal detection of ilarviruses using primers designed to the RNA-dependent RNA polymerase gene in RNA2. The assay detected 32 isolates of 15 definite and 2 tentative ilarvirus species using a one-step RT-PCR. The assay was more specific, and at least as sensitive as a commercial assay, and allowed direct sequencing of amplicons. No cross-reaction was observed with neither healthy plants of 15 host species nor from isolates in other genera of the Bromoviridae. A further PCR assay targeting the helicase motif of RNA1 was able to detect all species tested within the family Bromoviridae, including members of the Alfamovirus, Anulavirus, Bromovirus, Cucumovirus and Ilarvirus. The assays provide a sensitive and cost-effective way for detecting and characterising members of the Bromoviridae and can be used for quarantine and certification programmes.
